What is axon reflex?

The axon reflex is a neural response that occurs when sensory nerve fibers (axons) are stimulated, leading to the transmission of signals away from the point of stimulation. This reflex mechanism involves the release of neurotransmitters at the nerve endings, which then activate neighboring sensory or motor neurons.

In simpler terms, when a sensory nerve is stimulated, it can trigger a response in nearby nerves without involving the brain or spinal cord. This allows for rapid and automatic reactions to certain stimuli, such as pain or itchiness. The axon reflex is involved in various physiological processes, including pain perception, inflammation, and the regulation of blood flow.
